2. This section presents the Characteristics of the OSRAM GR CSSRML.24 device, measured under the conditions of IF​=350 mA and TJ​=25 ∘C. In terms of optical performance, the device has a typical peak wavelength (λpeak​) of 640 nm, while the dominant wavelength (λdom​) ranges from a minimum of 620 nm to a maximum of 636 nm, with a typical value of 630 nm at IF​=350 mA. The spectral bandwidth (Δλ) at 50% relative maximum intensity is 15 nm (typical), paired with a wide viewing angle (2φ) of 120° (typical) at 50% luminous intensity. For electrical characteristics, the forward voltage (VF​) at IF​=350 mA spans from a minimum of 1.90 V to a maximum of 2.20 V, with a typical value of 2.09 V; the device is explicitly noted as "Not designed for reverse operation" under the reverse current (IR​) parameter. Additionally, the electrical thermal resistance from the junction to the solder point (RthJS elec.​) is 2.1 K/W (typical), achieved with an efficiency (ηe​) of 66%, supporting efficient thermal management during operation.

3. This section of the OSRAM GR CSSRML.24 datasheet outlines the Brightness Groups, defined by key optical and efficiency metrics measured at IF​=350 mA. Four brightness groups are specified: TO, UJ, UK, and UL, each with distinct ranges for total radiant flux (ΦE​), Photosynthetic Photon Flux (PPF, Φp​), and Photon Flux (PF, Φp,b​). Group TO has a total radiant flux range of 415–450 mW, with PPF spanning 2.21–2.40 µmol/s (typical PPF/W of 3.15 µmol/J) and PF spanning 2.21–2.40 µmol/s (typical PF/W of 3.15 µmol/J). Group UJ covers a total radiant flux of 450–485 mW, with PPF of 2.40–2.58 µmol/s (typical PPF/W of 3.40 µmol/J) and PF of 2.40–2.58 µmol/s (typical PF/W of 3.41 µmol/J). Group UK offers a total radiant flux of 485–525 mW, PPF of 2.58–2.79 µmol/s (typical PPF/W of 3.67 µmol/J), and PF of 2.58–2.80 µmol/s (typical PF/W of 3.68 µmol/J). The highest-performing group, UL, provides a total radiant flux of 525–565 mW, PPF of 2.79–3.01 µmol/s (typical PPF/W of 3.97 µmol/J), and PF of 2.80–3.01 µmol/s (typical PF/W of 3.97 µmol/J). Accompanying notes clarify that PPF ([*]) accounts for wavelengths between 400 and 700 nm, while PF ([**]) includes wavelengths from 280 to 800 nm, and both PPF and PF values are provided for reference only, ensuring clear context for the photon flux measurements.

4. This section details the Forward Voltage Groups for the OSRAM GR CSSRML.24 device, defined by forward voltage (VF​) ranges measured at a forward current IF​=350 mA. Three distinct voltage groups are specified to categorize devices based on their electrical performance: Group E2 covers a forward voltage range from 1.90 V to 2.00 V, Group F1 spans from 2.00 V to 2.10 V, and Group F2 extends from 2.10 V to 2.20 V. These groupings enable precise binning of devices, ensuring consistent forward voltage characteristics within each packing unit, aligning with the overall forward voltage limits (minimum 1.90 V, maximum 2.20 V) outlined in the device’s core characteristics, and supporting reliable integration into target applications by providing clear, segmented electrical performance benchmarks.

5.This section outlines the Wavelength Groups for the OSRAM GR CSSRML.24 device, defined by dominant wavelength (λdom​) ranges measured at a forward current IF​=350 mA. Four distinct wavelength groups are specified to categorize devices based on their spectral performance: Group 4 covers a dominant wavelength range from 620 nm to 624 nm, Group 5 spans from 624 nm to 628 nm, Group 6 ranges from 628 nm to 632 nm, and Group 7 extends from 632 nm to 636 nm. These groupings enable precise binning of devices, ensuring consistent spectral output within each packing unit, aligning with the overall dominant wavelength limits (minimum 620 nm, maximum 636 nm) outlined in the device’s core characteristics, and supporting reliable integration into target applications by providing clear, segmented spectral performance benchmarks.
